Update alpine-linux to 3.14.5 - Zlib security FIX 3 years ago			`ARG DISTRO=alpine:3.14.5`
Add xapian full-text-search plugin to dovecot Currently we are not able to offer our users a FTS experience after the demise of lucene due to unfixed coredumps with musl/alpine. We now add lucene, the only remaining maintained small/lean FTS plugin for dovecot. It is quite simple to add to our stack: A two-stage docker build is used to compile the fts plugin in the first stage, and copy over only the resulting plugin-artifact to the second stage, which is our usual dovecot container. Configuration is also minimal. 5 years ago

upgrade alpine base-image 6 years ago			`# Shared layer between dovecot and postfix`
Switch from docker build to buildx for CI/CD. - The main workflow file has been optimised and simplified. - Images are built in parallel when building locally resulting in faster build times. - The github action workflow is about 50% faster. - Arm images are built as well. These images are not tested due to restrictions of github actions (no arm runners). The tags of the images have -arm appended to it. - Arm images can also be built locally. - Reusable workflow is introduced for building, testing and deploying the images. This allows the workflow to be reused for other purposes in the future. - Workflow can be manually triggered. This allows forked Mailu projects to also use the workflow for building images. 2 years ago			`RUN apk add --no-cache --virtual .build-deps gcc musl-dev python3-dev \`

use dovecot-fts-xapian from alpine package I suggest using the dovecot-fts-xapian package from the alpine repository (newer) instead of compiling an older version from source: see https://pkgs.alpinelinux.org/package/edge/community/x86/dovecot-fts-xapian 3 years ago			`dovecot dovecot-lmtpd dovecot-pop3d dovecot-submissiond dovecot-pigeonhole-plugin rspamd-client xapian-core dovecot-fts-xapian \`
Don't recursivly chown on mailboxes. This fixes #776. Recursion is not needed, as the permissions will only need to be set on the first invocation. 6 years ago			`&& mkdir /var/lib/dovecot`

add healthcheck for dovecot 6 years ago
Increase HEALTHCHECK start time for services that need to wait for host resolving during startup. In Docker Swarm mode the services listed below can get stuck in their start script, while they are waiting for other services become available. Now, with HEALTHCHECK enabled, docker does not resolve names of services that not pass HEALTHCHECK yet. Meaning that if one of the depenend services is not yet available, it will create a chain of failing services. The services below retry to resolve 100 time, with an average of 3.5 seconds. Hence, the --start-time flag is now set at 350 seconds. - dovecot (imap) - postfix (smtp) - rspamd (antispam) 6 years ago			`HEALTHCHECK --start-period=350s CMD echo QUIT\|nc localhost 110\|grep "Dovecot ready."`
Process code review remarks - Moved run to bottom of Dockerfile to allow using unmodified / cached states. - Simplified bash code in deploy.sh. - Improved the large bash one-liner in CI.yml. It could not handle >9 for 1.x. 3 years ago			`RUN echo $VERSION >> /version`
